On the depth of simplicial affine semigroup rings
Published 31 Jul 2023 in math.AC | (2307.16501v1)
Abstract: We recall and delve into the different characterizations of the depth of an affine semigroup ring, providing an original characterization of depth two in three and four dimensional cases which are closely related to the existence of a maximal element in certain Apery sets.
